The resource processing method comprises: receiving, by UE, first signaling from a base station, wherein the first signaling is used to instruct to deactivate a first cell that provides a service for the UE, or used to instruct the UE to switch from a source bandwidth part (BWP) to a target BWP; and processing, by a media access control (MAC) entity in the UE, a first target resource by using a first target processing manner, wherein the first target resource is a resource in the first cell or the source BWP.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation application of U.S. application Ser. No. 17/094,725 filed on Nov. 10, 2020, which is a continuation application of PCT Application No. PCT/CN2019/085814 filed on May 7, 2019, the PCT Application claims priority to Chinese Patent Application No. 201810450841.0, filed in China on May 11, 2018, disclosures of which are incorporated herein by reference in their entireties.

TECHNICAL FIELD

Embodiments of this disclosure relate to the communications field, and in particular, to a resource processing method, an apparatus, and a system.

BACKGROUND

In a communications system, user equipment (UE) may send a channel state information (CSI) report to a base station, so that the base station can obtain CSI based on the CSI report and schedule the UE based on the CSI.

Usually, the base station may configure a reference signal resource (for example, a CSI reference signal (CSI-RS) resource) for the UE or indicate a reference signal resource to the UE, so that the UE performs CSI measurement. After the UE obtains the reference signal resource configured or indicated by the base station, the UE may allocate a CSI processing unit to the reference signal resource, so that the UE performs a measurement process on the reference signal resource. After measuring the reference signal resource, the CSI processing unit may process (for example, calculate or analyze) a measurement result and generate a CSI report based on a processed result, and then the UE sends the CSI report to the base station.

However, when a cell on which the UE camps is deactivated, or a bandwidth part (BWP) in which the UE works is switched, according to the foregoing process, on one hand, because an occupied CSI processing unit can perform a measurement process only on a reference signal resource associated with a CSI report corresponding to the CSI processing unit, the CSI processing unit cannot perform a measurement process on other reference signal resources; on the other hand, because other resources related to this measurement process can be used only in this measurement process, these resources cannot be used in other processes. Therefore, resources (including the foregoing CSI processing unit and other resources) in the measurement process of the UE are wasted, and utilization of the resources in the measurement process of the UE is reduced.

SUMMARY

According to a first aspect, an embodiment of this disclosure provides a resource processing method. The method may include: receiving, by UE, first signaling from a base station, where the first signaling is used to instruct to deactivate a first cell that provides a service for the UE, or used to instruct the UE to switch from a source BWP to a target BWP; and processing, by a MAC entity in the UE, a first target resource by using a first target processing manner, where the first target resource is a resource in the first cell or the source BWP.

According to a second aspect, an embodiment of this disclosure provides UE. The UE includes a processor, a memory, and a computer program stored in the memory and capable of running on the processor. When the computer program is executed by the processor, the UE implements steps of the resource processing method in the first aspect.

According to a third aspect, an embodiment of this disclosure provides a non-transitory computer-readable storage medium. The non-transitory computer-readable storage medium stores a computer program, and the computer program is configured to be executed by a processor to cause UE to implement steps of the resource processing method in the first aspect.

DESCRIPTION OF EMBODIMENTS

The following clearly describes the technical solutions in the embodiments of this disclosure with reference to the accompanying drawings in the embodiments of this disclosure. Apparently, the described embodiments are some rather than all of the embodiments of this disclosure. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of this disclosure without creative efforts shall fall within the protection scope of this disclosure.

In the specification and claims of this disclosure, the terms “first” and “second” are used to distinguish between different objects, and are not used to describe a specific sequence of the objects. For example, a first processing manner and a second processing manner are used to distinguish between different processing manners, and are not used to describe a specific sequence of the processing manners. In the description of the embodiments of this disclosure, unless otherwise specified, “a plurality of” means two or more than two.

The term “and/or” in this specification describes an association relationship for describing associated objects and represents that three relationships may exist. For example, A and/or B may represent the following three cases: Only A exists, both A and B exist, and only B exists. The character “/” in this specification indicates an “or” relationship between the associated objects. For example, A/B indicates A or B.

In the embodiments of this disclosure, terms such as “exemplarily” or “for example” are used to represent examples, illustrations, or explanations. Any embodiment or design solution described as “exemplarily” or “for example” in the embodiments of this disclosure shall not be interpreted to be more preferential or advantageous than other embodiments or design solutions. Specifically, the terms such as “exemplarily” or “for example” are intended to present related concepts in a specific manner.

The following describes some concepts and/or terms used in a method for processing a CSI processing unit, a resource processing method, an apparatus, and a system provided in the embodiments of this disclosure.

CSI: namely channel state information. The CSI may include at least one of a channel quality indicator (CQI), a precoding matrix indicator (PMI), a CSI-RS resource indicator (CRI), a layer indicator (LI), a rank indicator (RI), and L1-reference signal received power (RSRP).

Periodic CSI report: It may refer to a CSI report periodically sent by UE to a base station. Specifically, a radio resource control (RRC) layer may configure parameters (for example, a period, a slot offset, and a symbol in a slot) of a periodic CSI report, and then the UE may transmit the periodic CSI report based on the parameters of the periodic CSI report by using an uplink control channel (for example, a long/short physical uplink control channel (PUCCH).

Aperiodic CSI report: It may refer to a CSI report sent by the UE to the base station based on an indication of the base station (for example, when receiving indication information sent by the base station). Specifically, the RRC layer may configure parameters (for example, a slot offset and a symbol in a slot) of an aperiodic CSI report, and then after the UE receives downlink control information (DCI) sent by the base station, the UE transmits the CSI report by using an uplink data channel (for example, a physical uplink shared channel (PUSCH)). For example, the CSI report may include reports on a plurality of component carriers and a plurality of types of reports (beam measurement report and CSI measurement report).

Semi-persistent CSI report: After the RRC layer configures parameters (for example, a period, a slot offset, and a symbol in a slot) of a semi-persistent CSI report, the UE may send the semi-persistent CSI report based on an indication (for example, activation or deactivation) of MAC CE signaling by using an uplink control channel; and/or after the UE receives DCI sent by the base station, the UE may send the semi-persistent CSI report by using an uplink data channel.

Bandwidth part (BWP): A cell served by the base station supports a large bandwidth (hereinafter referred to as the large bandwidth), but the UE may work in a plurality of small bandwidth parts (hereinafter referred to as the small bandwidth parts). A small bandwidth part in which UE within the large bandwidth can work is referred to as a BWP. Each BWP corresponds to a Numerology, a bandwidth, a frequency location (frequency location), and the like. Each BWP may include three control resource sets (CORESETs).

In the embodiments of this disclosure, it may be understand that a cell and a carrier are a same concept. Specifically, a carrier may be a carrier corresponding to a cell. For example, activating a cell may be understood as activating a carrier corresponding to the cell, and deactivating a cell may be understood as deactivating a carrier corresponding to the cell.

The embodiments of this disclosure provide a method for processing a CSI processing unit, a resource processing method, an apparatus, and a system. After UE receives first signaling sent by a base station, when target information (the target information includes at least the first signaling) satisfies a preset condition, the UE may process a first CSI processing unit by using a first processing manner corresponding to the target information. When performing a measurement process, the UE may determine different first processing manners based on different target information. Therefore, for different target information, the UE can process the first CSI processing unit by using different first processing manners, that is, the UE can control usage of the first CSI processing unit based on an actual requirement. Therefore, waste of CSI processing units in the measurement process of the UE can be reduced, and utilization of the CSI processing units in the measurement process of the UE can be increased.

In addition, after the UE receives first signaling sent by the base station, the UE may process a first target resource by using a first target processing manner. When performing a measurement process, the UE may process the first target resource by using different first target processing manners. Therefore, the UE can control usage of resources based on an actual requirement. Therefore, waste of resources in the measurement process of the UE can be reduced, and utilization of the resources in the measurement process of the UE can be increased.

The method for processing a CSI processing unit, the resource processing method, the apparatus, and the system provided in the embodiments of this disclosure may be applied to a communications system, and specifically, may be applied to resource processing in the measurement process of the UE based on the communications system.

For example, FIG. 1 is a schematic architectural diagram of a communications system according to an embodiment of this disclosure. As shown in FIG. 1, the communications system may include UE 01 and a base station 02. A connection may be established between the UE 01 and the base station 02.

It should be noted that in this embodiment of this disclosure, the connection between the UE 01 and the base station 02 shown in FIG. 1 may be a wireless connection. To indicate a connection relationship between the UE 01 and the base station 02 more clearly, a solid line is used in FIG. 1 to indicate the connection relationship between the UE 01 and the base station 02.

The UE is a device that provides a user with voice and/or data connectivity, for example, a handheld device with a wired or wireless connection function, or another processing device connected to a wireless modem. The UE may communicate with one or more core network devices by using a radio access network (RAN). The UE may be a mobile terminal, for example, a mobile phone (or referred to as a “cellular” phone) and a computer having a mobile terminal, or may be a portable, pocket-sized, handheld, computer built-in, or in-vehicle mobile apparatus, which exchanges voice and/or data with the RAN. For example, the UE is a device such as a personal communication service (PCS) phone, a cordless telephone set, a Session Initiation Protocol (SIP) phone, a wireless local loop (WLL) station, or a personal digital assistant (PDA). The UE may also be referred to as a user agent, a terminal device, or the like.

The base station is an apparatus deployed in the RAN and configured to provide a wireless communication function for the UE. The base station may include a macro base station, a micro base station, a relay station, an access point, and the like in various forms. A device with a base station function may have different names in systems using different radio access technologies. For example, the device is referred to as a NodeB in a third generation mobile communications (3G) network, or referred to as an evolved NodeB (eNB or eNodeB) in an LTE system. With evolution of communications technologies, the name “base station” may change.

The method for processing a CSI processing unit, the resource processing method, the apparatus, and the system provided in the embodiments of this disclosure are hereinafter described in detail with reference to the accompanying drawings by using specific embodiments and application scenarios thereof.

It should be noted that the method for processing a CSI processing unit and the resource processing method provided in the embodiments of this disclosure are hereinafter separately described in detail by using two specific embodiments (that is, Embodiment 1 and Embodiment 2).

Embodiment 1

Based on the communications system shown in FIG. 1, this embodiment of this disclosure provides a method for processing a CSI processing unit. As shown in FIG. 2, the method for processing a CSI processing unit may include the following step 201 to step 203.

Step 201: Abase station sends first signaling to UE.

In this embodiment of this disclosure, the first signaling may be used to instruct to deactivate a first cell that provides a service for the UE, or used to instruct the UE to switch from a source BWP to a target BWP.

In this embodiment of this disclosure, the first cell may be a cell that serves the UE.

Optionally, in this embodiment of this disclosure, the first signaling may be cell deactivation signaling or BWP switching signaling, where the cell deactivation signaling is used to instruct to deactivate the first cell, and the BWP switching signaling is used to instruct the UE to switch from the source BWP to the target BWP.

Optionally, in this embodiment of this disclosure, the BWP switching signaling may be used to instruct the UE to perform uplink BWP switching, or used to instruct the UE to perform downlink BWP switching, or used to instruct the UE to perform uplink BWP switching and downlink BWP switching. The BWP switching signaling used to instruct the UE to perform uplink BWP switching may be applied to a frequency division duplex (FDD) system. The BWP switching signaling used to instruct the UE to perform downlink BWP switching may also be applied to the FDD system. The BWP switching signaling used to instruct the UE to perform uplink BWP switching and downlink BWP switching may be applied to a time division duplex (TDD) system.

Optionally, in this embodiment of this disclosure, when the base station detects great interference (for example, the interference is greater than a first preset threshold), poor signal quality (for example, signal strength is less than a second preset threshold), and/or no service of the UE within preset duration in the first cell, the base station may send the first signaling (for example, the cell deactivation signaling) to the UE, so that the base station and the UE deactivate the first cell.

Optionally, in this embodiment of this disclosure, the base station may send RRC signaling or DCI to the UE, to instruct the UE to switch from the source BWP to the target BWP, where the RRC signaling carries the first signaling (for example, the BWP switching signaling), and the DCI carries the first signaling (for example, the BWP switching signaling).

For example, the base station may send DCI carrying the BWP switching signaling to the UE, to instruct the UE to switch from the source BWP (for example, a first CORESET in the source BWP) to the target BWP (for example, a second CORESET in the target BWP).

It may be understood that before the UE switches from the first CORESET to the second CORESET, the source BWP in which the first CORESET is located is a BWP in an active state; and after the UE switches from the first CORESET to the second CORESET, the target BWP in which the second CORESET is located is a BWP in an active state.

Step 202: The UE receives the first signaling sent by the base station.

Step 203: When target information satisfies a preset condition, the UE processes a first CSI processing unit by using a first processing manner corresponding to the target information.

In this embodiment of this disclosure, the target information includes at least the first signaling, the first CSI processing unit is a CSI processing unit for measuring a first downlink reference signal resource, and the first downlink reference signal resource is a downlink reference signal resource in the first cell or the source BWP.

In this embodiment of this disclosure, in a measurement process of the UE, after the UE receives first signaling, the UE may determine the target information, and determine whether the target information satisfies the preset condition; and when the UE determines that the target information satisfies the preset condition, the UE may process the first CSI processing unit by using the first processing manner corresponding to the target information.

In this embodiment of this disclosure, after the UE receives the first signaling sent by the base station, the UE may determine the target information based on the first signaling.

Optionally, in this embodiment of this disclosure, the first downlink reference signal resource may be a downlink reference signal resource in the first cell, and the downlink reference signal resource in the first cell may include at least one of a channel state information-reference signal (CSI-RS) resource in the first cell, a channel state information-interference measurement (CSI-IM) resource in the first cell, a synchronization signal block (SSB) resource in the first cell, and a zero power (ZP) CSI-RS resource set in the first cell.

Optionally, in this embodiment of this disclosure, the first downlink reference signal resource may be a downlink reference signal resource in the source BWP, and the downlink reference signal resource in the source BWP may include at least one of a CSI-RS resource in the source BWP, a CSI-IM resource in the source BWP, an SSB resource in the source BWP, and a ZP CSI-RS resource set in the source BWP.

For example, the CSI-RS resource may be a semi-persistent CSI-RS resource, the CSI-IM resource may be a semi-persistent CSI-IM resource, and the ZP CSI-RS resource set may be a semi-persistent ZP CSI-RS resource set.

It should be noted that the target information and the target information satisfying the preset condition are described in detail in the following embodiment and not described herein.

It should be noted that in this embodiment of this disclosure, measuring the first downlink reference signal resource by the first CSI processing unit may be understood as performing a measurement process on the first downlink reference signal resource by the first CSI processing unit, where the measurement process may be that the first CSI processing unit measures the first downlink reference signal resource, processes (for example, calculates and analyzes) a measurement result, and then generates a CSI report based on a processed result.

In the method for processing a CSI processing unit according to this embodiment of this disclosure, after the UE receives the first signaling sent by the base station, when the target information (the target information includes at least the first signaling) satisfies the preset condition, the UE may process the first CSI processing unit by using the first processing manner corresponding to the target information. When performing the measurement process, the UE may determine different first processing manners based on different target information. Therefore, for different target information, the UE can process the first CSI processing unit by using different first processing manners, that is, the UE can control usage of the first CSI processing unit based on an actual requirement. Therefore, waste of CSI processing units in the measurement process of the UE can be reduced, and utilization of the CSI processing units in the measurement process of the UE can be increased.

Optionally, in this embodiment of this disclosure, with reference to FIG. 2, as shown in FIG. 3, after the foregoing step 202, the method for processing a CSI processing unit according to this embodiment of this disclosure may further include the following step 301.

Step 301: The UE determines the target information based on the first signaling and indication information.

In this embodiment of this disclosure, the indication information may be first information indicated by the base station to the UE, or the indication information may be first information and second information indicated by the base station to the UE, the first information is used to indicate a type of a CSI report sent by the UE to the base station, the second information is used to indicate an uplink channel for sending the CSI report to the base station by the UE, and the CSI report includes a result of measuring the first downlink reference signal resource by the first CSI processing unit.

Optionally, in this embodiment of this disclosure, the first information may be used to indicate the type of the CSI report sent by the UE to the base station, and the CSI report may include a type-1 CSI report and a type-2 CSI report.

It should be noted that in this embodiment of this disclosure, the UE may determine the type of the CSI report based on received time domain action information, where the time domain action information may be sent by the base station by using RRC signaling. A time domain action may be periodic, semi-persistent, or aperiodic. In addition, the time domain action information may further include periodic duration, an aperiodic slot offset, and the like.

Optionally, in this embodiment of this disclosure, the second information may be used to indicate the uplink channel for sending the CSI report to the base station by the UE, and the uplink channel may be a target uplink channel.

Optionally, in this embodiment of this disclosure, the result of measuring the first downlink reference signal resource, which is included in the CSI report, may include a CSI type, codebook configurations (including a codebook subset restriction configuration and a group-based reporting configuration), the time domain action information, frequency domain granularities of a CQI and a PMI (CSI report band and whether a PMI/CQI report falls within a wideband or a sub-band), measurement restriction configurations, a configuration of time domain restriction for channel measurement (time restriction for channel measurements, time domain restriction for channel measurements), a configuration of time domain restriction for interference measurement (time restriction for interference measurements, time domain restriction for interference measurement), an LI, L1-RSRP, CRI, a synchronization signal block resource indicator (SSBRI), and the like.

Optionally, in a possible implementation of in this embodiment of this disclosure, after the UE receives the first signaling sent by the base station, the UE may determine the first signaling as the target information.

Optionally, in this embodiment of this disclosure, in a case that the target information includes the first signaling, that the target information satisfies the preset condition is: the first signaling is type-1 signaling; and the UE may process the first CSI processing unit by using the first processing manner corresponding to the first signaling.

Optionally, in this embodiment of this disclosure, in a case that the type-1 signaling is cell deactivation signaling, the first processing manner is releasing (clear/release) a CSI processing unit. With reference to FIG. 3, as shown in FIG. 4, the foregoing step 203 may be specifically implemented by the following step 203 a.

Step 203 a: When the target information satisfies the preset condition, the UE releases the first CSI processing unit.

In this embodiment of this disclosure, the first CSI processing unit in the foregoing step 203 a is a CSI processing unit for measuring a downlink reference signal resource in the first cell.

In this embodiment of this disclosure, when the target information includes the first signaling, the first signaling is the type-1 signaling, and the type-1 signaling is the cell deactivation signaling, the UE may release the first CSI processing unit.

It should be noted that in this embodiment of this disclosure, releasing may be understood as non-occupying. For example, releasing the first CSI processing unit by the UE may be understood as no longer occupying the first CSI processing unit by the UE.

In this embodiment of this disclosure, when the target information includes the first signaling, the first signaling is the type-1 signaling, and the type-1 signaling is the cell deactivation signaling, the UE may release the first CSI processing unit. Therefore, waste of the first CSI processing unit in the measurement process of the UE can be reduced, and utilization of the first CSI processing unit in the measurement process of the UE can be increased.

Optionally, in another possible implementation of this embodiment of this disclosure, the UE may determine the target information based on the first signaling and the first information.

Therefore, it can be ensured that the measurement process is normally completed, while the first CSI processing unit is not wasted.

Optionally, in still another possible implementation of this embodiment of this disclosure, the UE may determine the target information based on the first signaling, the first information, and the second information.

Optionally, in this embodiment of this disclosure, in a case that the target information includes the first signaling, the CSI report, and the uplink channel, that the target information satisfies the preset condition is: the first signaling is the type-2 signaling, and the CSI report is the type-2 CSI report, and the uplink channel is the target uplink channel; and the UE may process the first CSI processing unit by using the first processing manner corresponding to the first signaling, the CSI report, and the uplink channel.

It should be noted that in this embodiment of this disclosure, an execution sequence of step 401 and step 203 is not limited. Specifically, in an implementation, step 203 may be performed first, and then step 401 is performed. To be specific, the UE may first process the first CSI processing unit by using the first processing manner, and then process the first target resource by using the second processing manner. In another implementation, step 401 may be performed first, and then step 203 is performed. To be specific, the UE may first process the first target resource by using the second processing manner, and then process the first CSI processing unit by using the first processing manner. In still another implementation, step 203 and step 401 may be performed simultaneously. To be specific, the UE may simultaneously process the first CSI processing unit by using the first processing manner and process the first target resource by using the second processing manner.

In this embodiment of this disclosure, in the measurement process, after the UE receives first signaling, the UE may process the first target resource by using the second processing manner, and process the first CSI processing unit by using the first processing manner corresponding to the target information. Therefore, waste of resources (the first CSI processing unit and the first target resource) in the measurement process of the UE can be reduced, and utilization of the resources in the measurement process of the UE can be increased.

Optionally, in this embodiment of this disclosure, the first signaling is used to deactivate the first cell, and the first target resource is a resource in the first cell.

It should be noted that for descriptions about the second processing manner and the resource in the first cell, reference may be made to the descriptions in the foregoing embodiments. Details are not described again herein.

Step 501: The base station sends second signaling to the UE.

In this embodiment of this disclosure, the second signaling in the foregoing step 501 may be used to instruct to activate a second cell that provides a service for the UE, and the second cell is the same as or different from the first cell.

In this embodiment of this disclosure, the second cell may be a cell that serves the UE.

It may be understood that in this embodiment of this disclosure, when the UE camps on the first cell, the first cell is the cell that serves the UE; and when the UE camps on the second cell, the second cell is the cell that serves the UE.

In this embodiment of this disclosure, the base station may send the second signaling (for example, cell activation signaling) to the UE, so that the base station and the UE activate the second cell.

Step 502: The UE receives the second signaling sent by the base station.

Step 503: The UE processes a second target resource by using a third processing manner.

In this embodiment of this disclosure, the MAC entity in the UE may process the second target resource by using the third processing manner, and the second target resource is a resource in the second cell.

Optionally, in this embodiment of this disclosure, the second processing manner may be releasing a resource, releasing configuration information of a resource, or suspending a resource. The third processing manner is activating a resource based on an activation command sent by the base station, or activating or restoring a resource based on configuration information sent by the base station.

Optionally, in this embodiment of this disclosure, after the UE processes the first target resource by using the second processing manner, and the UE receives the second signaling, the UE may process the second target resource by using the third processing manner.

In this embodiment of this disclosure, in a case that the second target resource is in a released state before the UE receives the second signaling, the third processing manner used by the UE after the UE receives the second signaling is activating the second target resource; in a case that the second target resource is in a state of “configuration information released or deleted” before the UE receives the second signaling, the third processing manner used by the UE after the UE receives the second signaling is activating the second target resource based on configuration information sent by the base station; or in a case that the second target resource is in a suspended state before the UE receives the second signaling, the third processing manner used by the UE after the UE receives the second signaling is restoring the second target resource. Specifically, the third processing manner used by the UE after the UE receives the second signaling may be determined based on a specific status of the second target resource before the UE receives the second signaling. This is not limited in this embodiment of this disclosure.

Optionally, in this embodiment of this disclosure, the second target resource may include at least one of a target downlink reference signal resource, a target uplink reference signal resource, and an uplink channel for sending the CSI report to the base station by the UE, and the target downlink reference signal resource includes the first downlink reference signal resource.

In this embodiment of this disclosure, because the UE may process the first CSI processing unit by using the first processing manner, and may process the resource in the first cell by using the second processing manner, waste of the resources (the first CSI processing unit and the first target resource) in the measurement process of the UE can be reduced, and utilization of the resources in the measurement process of the UE can be increased; in addition, because the UE may process the second target resource (for example, the resource in the second cell) by using the third processing manner after the UE receives the second signaling (used to instruct to activate the second cell) sent by the base station, it can be ensured that the resource in the second cell can be normally used and it can be ensured that the measurement process of the UE can be normally performed.

It should be noted that for descriptions about the second processing manner and the resource in the source BWP, reference may be made to the descriptions in the foregoing embodiments. Details are not described again herein.

Step 601: After the UE completes switching, the base station sends second signaling to the UE.

In this embodiment of this disclosure, the second signaling in the foregoing step 601 may be used to instruct to activate a resource in the target BWP.

In this embodiment of this disclosure, completing switching by the UE may be understood as having switched from the source BWP to the target BWP by the UE and learning, by the base station, that the UE has switched from the source BWP to the target BWP.

Optionally, in this embodiment of this disclosure, the resource in the target BWP may include at least one of a target downlink reference signal resource in the target BWP, a target uplink reference signal resource in the target BWP, and an uplink channel for sending the CSI report to the base station by the UE in the target BWP.

Step 603: The UE processes a second target resource by using a third processing manner.

In this embodiment of this disclosure, the MAC entity in the UE may process the second target resource by using the third processing manner, and the second target resource is a resource in the target BWP.

It should be noted that for descriptions about the third processing manner and the resource in the target BWP, reference may be made to the descriptions in the foregoing embodiments. Details are not described again herein.

In this embodiment of this disclosure, because the UE may process the first CSI processing unit by using the first processing manner, and may process the resource in the first cell by using the second processing manner, waste of the resources (the first CSI processing unit and the first target resource) in the measurement process of the UE can be reduced, and utilization of the resources in the measurement process of the UE can be increased; in addition, because the UE may process the second target resource (for example, the resource in the target BWP) by using the third processing manner after the UE completes switching and receives the second signaling (used to instruct to activate the resource in the target BWP) sent by the base station, it can be ensured that the resource in the target BWP can be normally used and it can be ensured that the measurement process of the UE can be normally performed.

Optionally, in this embodiment of this disclosure, the first signaling may be used to instruct the UE to switch from the source BWP to the target BWP, and the first target resource is a resource in the source BWP. With reference to FIG. 8, as shown in FIG. 11, the foregoing step 401 may be specifically implemented by the following step 401 c, and after the foregoing step 401, the method for processing a CSI processing unit according to this embodiment of this disclosure may further include the following step 701.

Step 401 c: The UE processes a resource in the source BWP by using the second processing manner.

In this embodiment of this disclosure, the MAC entity in the UE may process the resource in the source BWP by using the second processing manner.

It should be noted that for descriptions about the second processing manner and the resource in the source BWP, reference may be made to the descriptions in the foregoing embodiments. Details are not described again herein.

In this embodiment of this disclosure, the MAC entity in the UE may process the second target resource by using the third processing manner, and the second target resource is a resource in the target BWP.

In this embodiment of this disclosure, because the UE may process the first CSI processing unit by using the first processing manner, and may process the resource in the first cell by using the second processing manner, waste of the resources (the first CSI processing unit and the first target resource) in the measurement process of the UE can be reduced, and utilization of the resources in the measurement process of the UE can be increased; in addition, because the UE may process the second target resource (for example, the resource in the target BWP) by using the third processing manner after the UE completes switching, it can be ensured that the resource in the target BWP can be normally used and it can be ensured that the measurement process of the UE can be normally performed.
